CYF1072V Datasheet | Cypress

Features - Functional Description The Cypress programmable FIFO family offers the industry’s highest-density programmable FIFO memory device. It has independent read and write ports, which can be clocked up to 100 MHz. User can configure input and output bus sizes. The maximum bus size of 36 bits enables a maximum data throughput of 3.6 Gbps. The read and write ports can support multiple I/O voltage standards. The user-programmable registers enable user to configure the device operation as desired. The device also offers a simple and easy-to-use interface to reduce implementation and debugging efforts, improve time-to-market, and reduce engineering costs. This makes it an ideal memory choice for a wide range of applications including multiprocessor interfaces, video and image processing, networking and telemunications, high-speed data acquisition, or any system that needs buffering at very high speeds across different domains. As implied by the name, the functionality of the FIFO is such that the data is read out of the read port in the same sequence in which it was written into the write port. The data is sequentially written into the FIFO from the write port. If the writes and inputs are enabled, the data on the write port gets written into the device at the rising edge of the write clock. Enabling the reads and outputs fetches data on the read port at every rising edge of the read clock. Both reads and writes can occur simultaneously at different speeds provided the ratio of read to write clock is between 0.5 and 2. Appropriate flags are set whenever the FIFO is empty or full. The device also supports two-Queue operation, mark and retransmit of data, and a flow-through mailbox register. All product features and specs are mon to all densities (CYF1072V, CYF1036V, and CYF1018V) unless otherwise specified. All descriptions are given assuming the device is CYF1072V operated in × 36 mode. They hold good for other densities (CYF1036V, and CYF1018V) and all port sizes...
